Definitions

  • the invention relates to a method for producing a connection between two optical lines, in which a reserve length of an optical waveguide is pulled out of a storage container and pushed back in after completion of the connection, and to an arrangement for carrying out this method.
  • each cable end is each accommodated individually in storage containers, from which reserve lengths are pulled out for direct connection of two ends of optical fibers and pushed back in again after making splice connections.
  • a considerable number of storage containers is required, which is twice the number of optical fibers of the optical cables. This number of storage containers is also to be provided if initially only a part of the optical waveguides is to be spliced together.
  • the invention has for its object to design the method of the type mentioned in such a way that the space requirement of the storage containers is reduced.
  • optical waveguides to be connected to the optical lines are each connected to one end of a marshalling line, each of which is pulled out of a single storage container and the excess lengths of which are pushed back into the storage container after the connections have been made.
  • a storage container of a flat design which is particularly suitable for the method according to the invention results from the fact that it has a substantially cylindrical core with a diameter of at least 40 mm, which is arranged centrally between two lateral guide surfaces, and that the distance h between the guide surfaces in the region d Z-h ⁇ 1.3 d, if d is the diameter of the patch cord, the patch cord is spirally wound in at least two turns in a plane around the core, that the end of the outermost turn is passed through an opening in a circumferential surface surrounding the core at a distance and that the end of the innermost turn from the turn space between the side guide surfaces is guided obliquely and over the remaining turns to a radially outside of the turn space guide eyelet. It is advantageous that the end of the innermost turn on the way to the at least approximate contact with the outer surface of the core is guided in a region outside the turn space in a guide channel.
  • a preferred embodiment is characterized in that the guide channel extends essentially concentrically to the core and, if appropriate, in the outer area thereof at a predetermined angular range, while the guide channel is guided via the windings outside the winding space in a parallel plane, preferably inside a guide wall.
  • At least one of the lateral guide walls consists of at least 3 tangentially spaced radial spoke-shaped webs, which are separated in the middle area by insertion slots which run obliquely to the tangent of the turns.
  • a smooth pushing in and pulling out the ends of the rag line is possible by pulling out or pushing back both ends simultaneously and evenly.
  • one end can advantageously be pulled out and the other end pushed into the storage container simultaneously or alternately in short lengths.
  • FIG. 1 2 of the receptacles for a shunting line with the ends 1 and 5 is designated.
  • Fibers with a fixed secondary coating that have an outside diameter of approximately 0.9 mm are particularly suitable as patch cords that contain only one optical fiber.
  • the housings 3 and 4 serve to accommodate splice connections, each with an optical waveguide of a first cable or a second cable.
  • the length of the patch cords should be selected according to the distances between the housings 3 and 4. For the majority of cases occurring in practice, it is sufficient if two lengths 1 and 5 of 0.5 m each can be pulled out on both sides of the receptacle, in which case the total length of the marshalling line, including the turns remaining inside is about 2 m.
  • the ends 1 and 5 are pulled out and pushed back into the housings 3 and 4 after the splice connections have been put down.
  • plug connections could also be selected instead of splice connections. Then the ends 1 and 5 would have to be provided with plug elements.
  • FIGS. 3 and 4 and 5 and 6 show receptacles which are specially adapted for the method according to the invention.
  • a minimum bending radius permissible for fiber optic cables must also not be undercut for the turns of the marshalling cables within the receptacles.
  • the shunting lines 14 and 15 are spirally wound in one plane in several turns, of which only three are shown for better visibility, around a core 16 and 17, respectively, the diameter of which is approximately 60 mm, so that even when the innermost ones are in close contact Winding at the core the minimum permissible bending radius is not exceeded.
  • the cores 16 and 17 connect in the middle each a rear guide wall 18 or 19 and front guide walls which are designed as narrow radial spokes 20 and 21 and are each interrupted by insertion slots 22 and 23, which run obliquely to the tangent of the turns, through which the Windings of the jumper cables 20 and 21 can be inserted.
  • the oblique course of the slots 22 and 23 prevents the turns from accidentally sliding out again.
  • the guide walls on both sides enclose a guide space with a small height h between them, which is slightly larger than the diameter of the patch cord and should not exceed about 1.3 times its diameter. Then a smooth, orderly and crossing-free guidance of the turns is guaranteed.
  • peripheral walls 28 and 29 can, for example, also be square, in which case the outermost windings rest at four points.
  • FIGS. 5 and 6 If several of the receptacles are to be stacked on top of one another according to FIG. 2, an embodiment according to FIGS. 5 and 6 is recommended.
  • the end 31 of the marshalling line 15 starting from the inner turn is guided up to point 32 into a guide channel which extends from the peripheral wall 29 to Circumferential surface of the core 17 extends in the guide wall 19, then is deflected within an adapted groove 33 in the core 17 obliquely or slightly curved S-shaped into the winding plane. This prevents any friction between the end 31 and the turns of the switching line 25 in the turn space.
  • the jumper lines 24 and 25 are normally inserted in such a way that approximately the same lengths can be pulled out on both sides.
  • the ends can be pulled out or pushed in particularly easily if both are moved simultaneously. If different lengths of the two ends are required, especially if only one end is too short for a distant connection point, this can be pulled out further if the other end is pushed in at the same time or alternately piece by piece.
  • d is the diameter of the core and D is the diameter of the peripheral walls 28 or 29 or the maximum possible diameter of the outermost turn.
  • d o is the diameter of the patch cord.
  • the value D should be selected as follows: This dimensioning results in the smallest possible dimensions.
